What is Lymphadenopathy (Enlarged Lymph Nodes)?
Lymphadenopathy refers to enlargement of one or more lymph nodes, which are small bean-shaped immune organs distributed throughout the body. Normal lymph nodes are typically less than 1 cm in diameter and barely palpable. When inflamed or infiltrated by abnormal cells, they enlarge and may become tender, firm, or fixed.
The pattern of involvement provides important diagnostic clues. Localized lymphadenopathy (one region) often reflects a nearby infection or local malignancy, while generalized lymphadenopathy (two or more non-contiguous regions) suggests systemic disease — viral infection, autoimmune disease, hematologic malignancy, or HIV.
Most lymphadenopathy in primary care is benign and reactive, especially in young patients with a recent upper respiratory infection. However, persistent (>4-6 weeks), progressive, hard, fixed, or supraclavicular adenopathy and B symptoms (fever, night sweats, weight loss) warrant urgent evaluation including imaging and tissue diagnosis.
Symptoms
Risk Factors
When to See a Doctor?
If you experience any of the following symptoms, seek medical attention promptly:
- Lymph node larger than 1 cm persisting for over 4-6 weeks
- Hard, fixed, or rapidly growing node
- Supraclavicular node (highly suggestive of malignancy)
- B symptoms: fever, night sweats, weight loss greater than 10% in 6 months
- Generalized lymphadenopathy without obvious cause
- Severe pain, redness, or fluctuance (abscess)
- Lymphadenopathy with splenomegaly or hepatomegaly
- Lymphadenopathy in immunosuppressed patient or known cancer history

Anaemia
Dahiliye (İç Hastalıkları)
Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.
Iron Deficiency Anaemia
Dahiliye (İç Hastalıkları)
Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.
Vitamin B12 Deficiency
Dahiliye (İç Hastalıkları)
Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.
Hypertension (High Blood Pressure) Management
Dahiliye (İç Hastalıkları)
Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.
Chronic Kidney Disease
Dahiliye (İç Hastalıkları)
Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.
Hepatitis B (HBV)
Dahiliye (İç Hastalıkları)
Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.
Hepatitis C (HCV)
Dahiliye (İç Hastalıkları)
Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.
Fatty Liver Disease
Dahiliye (İç Hastalıkları)
Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
